Applied changes by @KevinMenden from nf-core/tools#774 to avoid deprecated env usage and get CI tests working again.

Looks good to me! Was before already wondering why checks are failing.

me too :)

There was an error in the changes I made, you'll have to change the code slightly:
See here:
nf-core/tools#777

Basically exchange env.GIT_DIFF by env.MATCHED_FILES otherwise the docker image gets build all the time
